Description

Technical Field

[0001] The present invention generally relates to the field of balance rehabilitation training technology. More specifically, the present invention relates to a dynamic balance training method and system. Background Art

[0002] Dynamic balance refers to the ability to keep the body stable during movement, while the patient's perception involves the perception of body position, movement, and space. The relationship between the two is very close. When a patient's dynamic balance ability is impaired, their perception ability may also be affected. Dynamic balance has an important impact on the patient's perception ability. When a person's dynamic balance ability declines, it will greatly affect their body movement and normal life. Therefore, it is necessary to comprehensively consider the impact of dynamic balance and patient perception, and adopt targeted rehabilitation training and treatment to help patients restore or improve their balance and perception abilities, thereby improving their quality of life and sports performance.

[0003] In the prior art, a dynamic balance training device is usually used to perform balance training on the human body. During training, the user holds the handrail of the dynamic balance training device tightly and stands on the pedal of the dynamic balance training device to exert force on the legs, driving the pedal to swing, thereby performing balance training. However, for users with weak lower limb muscle strength, the training effect of using this dynamic balance training device is poor, resulting in poor balance training effect. For example, an active balance training device disclosed in a Chinese patent with authorization announcement number CN110180135 B includes a base, handrails, a swing mechanism, a pedal arranged above the base, and a swing mechanism arranged at the bottom of the pedal. When the user performs training, the user holds the handrail tightly and exerts force on the legs to drive the swing structure to swing, thereby driving the pedal to swing. For users with weak lower limb muscle strength, training is more laborious and may lead to exhaustion, and the balance training effect is poor. Summary of the invention

[0004] In order to solve the technical problem that the existing body balance training methods have poor training effects, the present invention provides solutions in the following aspects.

[0005] In a first aspect, the present invention provides a dynamic balance training method based on a dynamic balance training device, comprising: controlling a supporting plate of the dynamic balance training device to swing a first preset number of times, randomly selecting a direction to swing each time; one swing includes a process in which the supporting plate changes from a horizontal state to an inclined state and a process in which the supporting plate recovers from an inclined state to a horizontal state; the supporting plate is a flat plate for supporting a human body; in response to the supporting plate swinging a number of times reaching the first preset number of times, controlling the supporting plate to recover to a horizontal state, and obtaining the inclination direction of the user's body; controlling the supporting plate of the dynamic balance training device to swing a second preset number of times, the angle of each swing being a preset angle, and the swinging in the inclination direction and the swinging in the opposite direction of the inclination direction are performed alternately during the swinging.

[0006] The beneficial effects are as follows: the dynamic balance training method of the present invention first makes the supporting plate of the dynamic balance training device randomly swing in multiple directions for multiple times, then restores the supporting plate to a horizontal state, and obtains the tilt direction of the user's body. The direction in which the user's body is tilted indicates that the user's body balance and perception abilities in this direction are poor (i.e., a vertigo test is performed on the user), and balance training in this direction needs to be strengthened; during training, balance training is only performed in this direction, thereby greatly improving the efficiency of balance training.

[0007] In one embodiment, obtaining the tilt direction of the user's body includes:

[0008] A rectangular coordinate system is established by taking the center of the carrier plate as the origin, a horizontal straight line extending from the origin to the left and right as the x-axis, and the right as the direction of the x-axis, and a horizontal straight line extending from the origin to the front and back as the y-axis, and the front as the direction of the y-axis;

[0009] Collecting pressure data of the four corners of the carrying plate, and then calculating the position coordinates of the center of gravity of the user according to the pressure data of the four corners;

[0010] If the center of gravity is located on the positive half axis of the x-axis, it is determined that the user's body is tilted to the right; if the center of gravity is located on the negative half axis of the x-axis, it is determined that the user's body is tilted to the left; if the center of gravity is located on the positive half axis of the y-axis, it is determined that the user's body is tilted to the front; if the center of gravity is located on the negative half axis of the y-axis, it is determined that the user's body is tilted to the rear; if the center of gravity is located in the first quadrant of the coordinate axis, it is determined that the user's body is tilted to the right front; if the center of gravity is located in the second quadrant of the coordinate axis, it is determined that the user's body is tilted to the left front; if the center of gravity is located in the third quadrant of the coordinate axis, it is determined that the user's body is tilted to the left rear; if the center of gravity is located in the fourth quadrant of the coordinate axis, it is determined that the user's body is tilted to the right rear.

[0011] In one embodiment, the position coordinates of the center of gravity are expressed as:

[0012]

[0013]

[0014] Wherein, X represents the x-axis coordinate of the center of gravity in the rectangular coordinate system, Y represents the y-axis coordinate of the center of gravity in the rectangular coordinate system, and W all represents the sum of the pressure data of the four corners of the bearing plate, W A represents the pressure data of the right rear corner of the carrier plate, W B represents the pressure data of the left rear corner of the carrier plate, W C represents the pressure data of the left front corner of the carrier plate, W D represents the pressure data of the right front corner of the carrier plate, M represents the length of the carrier plate along the x-axis direction of the rectangular coordinate system, and N represents the length of the carrier plate along the y-axis direction of the rectangular coordinate system.

[0015] In one embodiment, during a swing process, the baseline time is 2 to 4 seconds, the holding time is 1 to 2 seconds, and the return time is 1 second. The baseline time refers to the time it takes for the support plate to tilt from a horizontal state to a preset angle, the holding time refers to the time it takes for the support plate to remain stationary after tilting to a preset angle, and the return time refers to the time it takes for the support plate to return to a horizontal state from a tilted state.

[0016] The beneficial effect is that by setting the baseline time to 2-4s, the holding time to 1-2s, and the return time to 1s, the load-bearing plate can be prevented from swinging too fast, causing discomfort to the human body, thereby achieving a better training effect for the user.

[0017] In one embodiment, the calculation expression of the preset angle is:

[0018]

[0019] In the formula, α represents a preset angle, θ represents a swing angle reference value, X represents the x-axis coordinate of the center of gravity in the rectangular coordinate system, Y represents the y-axis coordinate of the center of gravity in the rectangular coordinate system, M represents the length of the supporting plate along the x-axis direction in the rectangular coordinate system, and N represents the length of the supporting plate along the y-axis direction in the rectangular coordinate system.

[0020] The beneficial effects are as follows: the greater the angle at which the user's body tilts in a certain direction after the dizziness test, the greater the degree of dizziness of the user; the preset angle of the swing of the supporting plate is calculated by using the calculation expression of the preset angle of this embodiment, so that the greater the angle at which the user's body tilts in a certain direction after the dizziness test, the smaller the swing amplitude of the supporting plate in that direction during training, thereby preventing the user from falling from the supporting plate and ensuring safety during training.

[0021] In a second aspect, the present invention provides a dynamic balance training system, comprising: a host computer and a dynamic balance training device, the host computer comprising a memory and a processor, the processor controlling the connection to the dynamic balance training device, the memory storing computer program instructions, and the dynamic balance training method of the present invention is implemented when the computer program instructions are executed by the processor.

[0022] In one embodiment, the dynamic balance training device includes: a load-bearing plate for carrying a human body; a vertical rod, one end of which is fixedly connected to the center of the load-bearing plate, and the other end is movably connected to the base through a first connecting structure, so that the vertical rod can be tilted in all directions and the inclination angle is less than a preset value; a first electric push rod, a telescopic end of which is slidably connected to the vertical rod, and a fixed end of which is hinged on the bracket, so that the first electric push rod can rotate around a hinge point in a horizontal plane; a second electric push rod, a telescopic end of which is slidably connected to the vertical rod, and a fixed end of which is hinged on the bracket, so that the second electric push rod can rotate around a hinge point in a horizontal plane.

[0023] The beneficial effects are as follows: the traditional vertigo training device requires the user to stand on the pedal and actively exert force to make the body shake, thereby exercising the user's body balance ability. The dynamic balance training device of the present invention can drive the vertical rod to tilt in all directions by controlling the telescopic action of the first electric push rod and the second electric push rod, thereby driving the load-bearing board to tilt in all directions; after the user stands on the load-bearing board, the user's body can be moved in different spatial positions by balancing the balance board, thereby performing a series of training and exercises on the user's body balance ability and improving his or her perception of body position, movement and space; by setting a limit mechanism in the first connection structure to make the vertical rod tilt angle less than the preset value, the load-bearing board is prevented from tilting at too large an angle, causing the user standing on the load-bearing board to fall, thereby improving safety. The dynamic balance training device of the present invention has a simple structure and stable and reliable operation. The use of the dynamic balance training device of the present invention can effectively improve the training effect of the user's body balance ability rehabilitation training.

[0024] In one embodiment, the first connecting structure includes a spherical sliding block fixedly connected to one end of the vertical rod and a groove arranged on the base, the spherical sliding block is placed inside the groove and can slide along the inner surface of the groove, the inner surface of the groove is a curved surface, and the upper edge of the groove can limit the vertical rod so that the maximum inclination angle of the vertical rod is less than the preset first angle.

[0025] The beneficial effect is that, through the cooperation of the spherical sliding block and the groove, the vertical rod can be tilted in all directions without being subjected to excessive force in the horizontal direction.

[0026] In one embodiment, a pressure sensor is respectively disposed at the four corners of the bottom of the carrying plate to collect the pressure at the four corners of the bottom of the carrying plate.

[0027] In one embodiment, a ring is fixed to the telescopic end of the first electric push rod and the telescopic end of the second electric push rod respectively. The ring is sleeved on the vertical rod, and the inner diameter of the ring is larger than the outer diameter of the vertical rod. The ring can slide along the surface of the vertical rod.

[0028] The beneficial effect is that since the telescopic end of the electric push rod is connected to the vertical rod, a circular ring is sleeved on the vertical rod so that the telescopic end of the electric push rod is slidably connected to the circular ring, and the inner diameter of the circular ring is larger than the outer diameter of the vertical rod, thereby ensuring that when the electric push rod pushes the vertical rod, the vertical rod will not encounter too much resistance when tilting in the corresponding direction.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0035] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Embodiment of the dynamic balance training method based on the dynamic balance training device:

[0037] like Figure 1 As shown, the dynamic balance training method based on the dynamic balance training device of the present invention includes:

[0038] S101, causing the load-bearing plate of the dynamic balance training device to swing a first preset number of times, specifically: controlling the load-bearing plate of the dynamic balance training device to swing a first preset number of times, randomly selecting a direction to swing each time; one swing includes a process of the load-bearing plate changing from a horizontal state to an inclined state and a process of the load-bearing plate returning from an inclined state to a horizontal state; the load-bearing plate is a flat plate used to bear a human body;

[0039] The bearing plate of the dynamic balance training device can swing in various directions, thereby making the human body tilt in various directions.

[0040] S102, obtaining the tilt direction of the user's body, specifically: in response to the number of swings of the supporting plate reaching the first preset number, controlling the supporting plate to return to a horizontal state, and obtaining the tilt direction of the user's body;

[0041] S103, performing balance training on the user, specifically: controlling the support plate of the dynamic balance training device to swing a second preset number of times, each swinging angle being a preset angle, and swinging in the tilt direction and in the opposite direction of the tilt direction are performed alternately.

[0042] The dynamic balance training method of the present invention first makes the supporting plate of the dynamic balance training device randomly swing in multiple directions for multiple times, then restores the supporting plate to a horizontal state, and obtains the tilt direction of the user's body. The direction in which the user's body is tilted indicates that the user's body balance and perception abilities in this direction are poor (i.e., a vertigo test is performed on the user), and balance training in this direction needs to be strengthened; during training, balance training is only performed in this direction, thereby greatly improving the efficiency of balance training.

[0043] In one embodiment, obtaining the tilt direction of the user's body includes:

[0044] S201, taking the center of the carrying plate as the origin, a horizontal straight line extending in the left-right direction through the origin as the x-axis, and the right as the direction of the x-axis, taking the horizontal straight line extending in the front-back direction through the origin as the y-axis, and the front as the direction of the y-axis, thereby establishing a rectangular coordinate system;

[0045] S202, collecting pressure data of the four corners of the carrying plate, and then calculating the position coordinates of the center of gravity of the user according to the pressure data of the four corners;

[0046] By collecting the pressure data of the four corners of the support plate, the projection of the user's center of gravity on the static balance board can be calculated, and the coordinates of the projection can be used as the position coordinates of the user's center of gravity.

[0047] S203. If the center of gravity is located on the positive half axis of the x-axis, it is determined that the user's body is tilted to the right; if the center of gravity is located on the negative half axis of the x-axis, it is determined that the user's body is tilted to the left; if the center of gravity is located on the positive half axis of the y-axis, it is determined that the user's body is tilted to the front; if the center of gravity is located on the negative half axis of the y-axis, it is determined that the user's body is tilted to the rear; if the center of gravity is located in the first quadrant of the coordinate axis, it is determined that the user's body is tilted to the right front; if the center of gravity is located in the second quadrant of the coordinate axis, it is determined that the user's body is tilted to the left front; if the center of gravity is located in the third quadrant of the coordinate axis, it is determined that the user's body is tilted to the left rear; if the center of gravity is located in the fourth quadrant of the coordinate axis, it is determined that the user's body is tilted to the right rear.

[0048] In one embodiment, the position coordinates of the center of gravity are expressed as:

[0049]

[0050] Wherein, X represents the x-axis coordinate of the center of gravity in the rectangular coordinate system, Y represents the y-axis coordinate of the center of gravity in the rectangular coordinate system, and W all represents the sum of the pressure data of the four corners of the bearing plate, W A represents the pressure data of the right rear corner of the carrier plate, W B represents the pressure data of the left rear corner of the carrier plate, W C represents the pressure data of the left front corner of the carrier plate, W D represents the pressure data of the right front corner of the carrier plate, M represents the length of the carrier plate along the x-axis direction of the rectangular coordinate system, and N represents the length of the carrier plate along the y-axis direction of the rectangular coordinate system.

[0051] In one embodiment, during a swing process, the baseline time is 2 to 4 seconds, the holding time is 1 to 2 seconds, and the return time is 1 second. The baseline time refers to the time it takes for the support plate to tilt from a horizontal state to a preset angle, the holding time refers to the time it takes for the support plate to remain stationary after tilting to a preset angle, and the return time refers to the time it takes for the support plate to return to a horizontal state from a tilted state.

[0052] By setting the baseline time to 2 to 4 seconds, the holding time to 1 to 2 seconds, and the return time to 1 second, it is possible to avoid the support plate from swinging too fast, causing discomfort to the human body, thereby achieving a better training effect for the user.

[0053] In one embodiment, the preset angle ranges from 0 to 12 degrees.

[0054] In one embodiment, the calculation expression of the preset angle is:

[0055]

[0056] In the formula, α represents a preset angle, θ represents a swing angle reference value, X represents the x-axis coordinate of the center of gravity in the rectangular coordinate system, Y represents the y-axis coordinate of the center of gravity in the rectangular coordinate system, M represents the length of the supporting plate along the x-axis direction in the rectangular coordinate system, and N represents the length of the supporting plate along the y-axis direction in the rectangular coordinate system.

[0057] The greater the angle at which the user's body tilts in a certain direction after the dizziness test, the greater the degree of dizziness of the user; using the calculation expression of the preset angle of this embodiment to calculate the preset angle of the swing of the supporting plate, the greater the angle at which the user's body tilts in a certain direction after the dizziness test, the smaller the swing amplitude of the supporting plate in that direction during training, thereby preventing the user from falling from the supporting plate and ensuring safety during training.

[0058] Dynamic balance training system embodiment:

[0059] like Figure 2 As shown, the present invention also provides a dynamic balance training system, including: a host computer and a dynamic balance training device, the host computer includes a memory and a processor, the processor controls the connection to the dynamic balance training device, the memory stores computer program instructions, and when the computer program instructions are executed by the processor, the dynamic balance training method in the above-mentioned dynamic balance training method embodiment is implemented.

[0061] In order to facilitate the acquisition of the tilt angle of the carrying plate, a gyroscope can be installed on the carrying plate.

[0062] Traditional vertigo training devices require users to stand on the pedals and actively exert force to make the body shake, thereby exercising the user's body balance ability. The dynamic balance training device of the present invention can drive the vertical rod to tilt in all directions by controlling the telescopic action of the first electric push rod and the second electric push rod, thereby driving the load-bearing board to tilt in all directions; after the user stands on the load-bearing board, the balance board is disturbed to make the user's body move in different spatial positions, thereby performing a series of training and exercises on the user's body balance ability and improving his or her perception of body position, movement and space; by setting a limit mechanism in the first connection structure to make the vertical rod tilt angle less than the preset value, it is prevented that the load-bearing board is tilted at too large an angle, causing the user standing on the load-bearing board to fall, thereby improving safety. The dynamic balance training device of the present invention has a simple structure and stable and reliable operation. The dynamic balance training device of the present invention can effectively improve the training effect of the user's body balance ability rehabilitation training.

[0063] In one embodiment, the first connecting structure includes a spherical sliding block 6 fixedly connected to one end of the vertical rod and a groove 7 arranged on the base, the spherical sliding block is placed inside the groove and can slide along the inner surface of the groove, the inner surface of the groove is a curved surface, and the upper edge of the groove can limit the vertical rod so that the maximum inclination angle of the vertical rod is less than the preset first angle.

[0064] By making the upper edge of the groove protrude, the vertical rod can be limited to prevent its tilt angle from being too large. In this embodiment, the upper edge of the groove protrudes beyond the horizontal direction, and in other embodiments, it can also protrude in other directions. In this embodiment, the sliding block 6 is spherical, and the groove 7 is spherical or ellipsoidal.

[0065] Through the cooperation of the spherical sliding block and the groove, the vertical rod can be tilted in all directions without being subjected to excessive force in the horizontal direction.

[0068] In one embodiment, a ring 8 is fixed to the telescopic end of the first electric push rod and the telescopic end of the second electric push rod respectively. The ring is sleeved on the vertical rod 2, and the inner diameter of the ring is larger than the outer diameter of the vertical rod. The ring can slide along the surface of the vertical rod.

[0069] Since the telescopic end of the electric push rod is connected to the vertical rod, a circular ring is used to sleeve the vertical rod so that the telescopic end of the electric push rod is slidably connected to the circular ring, and the inner diameter of the circular ring is larger than the outer diameter of the vertical rod, thereby ensuring that when the electric push rod pushes the vertical rod, the vertical rod will not encounter too much resistance when tilting in the corresponding direction.
